The spraying program against the red-headed pine sawfly, Neodiprion lecontei (Fitch), has been carried out in 43 red pine plantations of the Dutaouais administrative region. The nuclear polyhedrosis virus of the red-headed pine sawfly has been used to control the pest on 330 hectares. Plantations with more than 10 per cent of the trees damaged in 1978 were subjected to the treatment.
